Reality According to the Holy Scriptures

First: proof (from within the Bible itself in this case) that the Holy Scriptures are 'Holy' and of God /through the Holy Spirit...

• Isaiah 8:20 King James Version (KJV) 20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
• Psalm 119:105 King James Version (KJV) 105 Thy word is a lamp unto my feet, and a light unto my path.
• Proverbs 30:5-6 King James Version (KJV) 5 Every word of God is pure: he is a shield unto them that put their trust in him. 6 Add thou not unto his words, lest he reprove thee, and thou be found a liar.
• John 17:17 King James Version (KJV) 17 Sanctify them through thy truth: thy word is truth.
• 1 Thessalonians 2:13 New American Standard Bible (NASB) 13 For this reason we also constantly thank God that when you received the word of God which you heard from us, you accepted it not as the word of men, but for what it really is, the word of God, which also performs its work in you who believe.
• 2 Timothy 3:16-17 New American Standard Bible (NASB) 16 All Scripture is [a]inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; 17 so that the man of God may be adequate, equipped for every good work.
• Hebrews 4:12 New American Standard Bible (NASB) 12 For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.
• 2 Peter 1:20-21 New American Standard Bible (NASB) 20 But know this first of all, that no prophecy of Scripture is a matter of one’s own interpretation, 21 for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God.

Now, the main topic: Reality as we know it according to God Himself speaking to us in the scriptures...

• Genesis 1:7 New American Standard Bible (NASB)
  7 Then the Lord God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being.
• Ecclesiastes 12:7 New American Standard Bible (NASB)
  7 then the dust will return to the earth as it was, and the spirit will return to God who gave it.

So, technically speaking we're really made of star stuff. All the basic minerals on Earth exist in the stars and other planets (Mars for example). In addition, many other minerals perhaps we don't have (or haven't discovered) here on Earth. 

• Genesis 1:3 New American Standard Bible (NASB) 3 Then God said, “Let there be light”; and there was light...6 Then God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters...”

God created (spoke into existence)  all that we know as the universe(s) during the phase of His process of creation of 6 days. All that would ever form, develop, and transform, that would ever need to exist in within His plans for all that exist. All the atoms, minerals, to all the living organisms of our bodies, which are meaningless without the breath of life that contains our conscious. That's hard to imagine possible as it sounds.
